I'm not a musicologist, so the following reflections are based on my personal impressions as well as booklets included in various CD's.
Start with Saint-Saëns 3rd (1886). This well known work made a great impression on Widor, who warmly praised Saint-Saëns's talent as on orchestrator. Widor's answer was his own 3rd symphony Op. 69 (https://youtu.be/mjCWX1xRUZk?si=b9YQZDcEs7ItCwhq), with organ and in two distinct parts as Saint-Saëns (1893). Widor's was performed in Paris in 1895, with Vierne at the organ. I don't think that the structure of Vierne's symphony (four movements in two parts) and the closeness of the theme of the scherzo to that of Widor's 3rd scherzo are coincidental.
It can be added that Vierne's symphony is dedicated to Gabriel Fauré.
Still missing is a recording of his Ballade for violin and orchestra Op. 52.
